DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 657,618, datedSeptember 11, 1900. Application filed April 13, 1899. Serial No.712,926. kNo model.)

To all whom it may concern:

Be it known that I, JAY B. RHODES, a citizen of the United States,residing at Harvey, in the county of Cook, State of Illinois, haveinvented a certain new and useful Improvement in Dumping-Cars, of whichthe following is a specification.

My invention relates more particularly to a construction of dumping-carin which the receptacle is tilted sidewise for the purpose of dumpingthe load and in which such tilting of the receptacle serves toautomatically operate or release the side board at whichever side of thecar the load is to be dumped.

The objects of my invention are to provide a simple and efficientconstruction of dumping-car involving a Well-balanced and easilytiltedreceptacle and to so counterbalance the load and receptacle during thetilting of the latter that the dumping angle will be reached withoutshock or jar and without danger of throwing the car off the track, tostrengthen the side portions of the receptacle without materiallyincreasing the weight of the latter, and to provide certain noveldetails tending to increase the general efficiency and serviceability ofcars of this class.

To the attainment of the foregoing and other useful ends my inventionconsists in matters hereinafter set forth and claimed.

In the accompanying drawings, Figure 1' is an end elevation of adumping-car embody ing the different features of my invention. Fig. 2 isa similar view of the same, but showing the receptacle partially tiltedto one side. Fig. 3 is a side elevation of the car shown in Figs. 1 and2. Figs. 4 and 5 are detail views of one of the truss-blocks.

A dumping-car constructed in accordance with my invention comprises ingeneral a truck or body frame A, supported upon carwheels l,a tiltingreceptacle B, mounted upon the said truck or body frame, and a couple ofautomatic side boards 0, arranged to nor mally close the open sides ofthe tilting receptacle. preferably composed of a couple of I-beams a,arranged to rest upon the journal-boxes, and a plurality of cross-beamsa,secured upon the upper surfaces of the said I-beams. In

The truck or body frame A is addition to the two side boards the tiltingreceptacle is preferably provided with end boards b, and its floor orbottom I) is adapted to receive and carry the load. The said receptacleis constructed to tilt about a longitudinal axis, so as to permit theload to be dumped or discharged at either side of the track, and Whilevarious arrangements may be adopted to secure such tilting action on thepart of the receptacle I prefer to connect the latter with thetruck-frame by means of suitable pivot-bearings a Thus pivotally mountedthe receptacle maybe readily tilted to either side for the purpose ofdischarging its load, and as a simple and convenient arrangement fornormally maintaining the receptacle in a horizontal position I connectthe latter with the truck or body frame by means of a number ofstay-chains 2.

The automatic side boards, which serve to close the open sides of thereceptacle when the latter is in its normal or horizontal position, areprovided with arms 0, having their inner ends pivotally connected withthe end boards I), and it will be observed that the side boards by suchprovision are arranged to swing about an axis c',which is directly abovethe axis afforded by the pivot-bearings a Ordinarily both side boardsrest upon the edge portions of the floorb, as shown in Fig. 1; but tofacilitate loading either side board may be swung over and allowed totemporarily rest upon the opposite side of the car, the'said board beingof course returned to its normal position as soon as the receptacle hasbecome filled and a closure of that side of the latter then becomesnecessary to complete the loading. Preferably the tilting of thereceptacle serves to automatically operate or release the side board atwhichever side of the car it is desired to dump, and to this end Iprovide the stops a which serve to prevent a downward movement of oneside board when the receptacle is tilted, and as a matter of furtherimprovement the said stops con sist of rolls suitably mounted upontransversely-arranged frames at, the latter being in turn supported byand suitably secured upon the end portions of the I-beams a. The rolls aare preferably grooved and adapted When it is desired to dump ordischarge the load at one side of the car, thestay-chains at theopposite side of the latter are first released and the receptacle thentilted over sufficiently to permit the load to slide out, it

being observed that during such operation the side board on thedescending side of the receptacle is released therefrom and supportedby. the rolls a while the other side board is simply carried up andallowed to remain in place. As the axis about which the receptacle tiltsis located somewhatbelow the latter, a slight push will therefore besufficient to start the loaded receptacle over to one side, and whileordinarilyin cars of this class the tilting movement of the receptaclehas terminated suddenly and with an objectionable shock or jolt it willbe seen that with my arrangement the weight of the load when tilted toone side is counterbalanced by the weight of the released .side boardand, moreover, that the leverage thus exerted by the latter increases asthe receptacle tilts. In Fig. 2 the receptacle is shown as partiallytilted to the left, the side board at the left being supported by therolls or stops a and in such position it will be readily seen that eacharm a of the side board when thus supported becomes a lever,with a-stopor roll a for a fulcrum. The farther the receptacle tilts the nearerthepivotal points of the arms are brought to the rolls a the leveragethereby increasing constantly and the receptacle in this way beingpermitted to tilt over and reach the dumping angle without shock or jar.It will be seen, therefore, that while I employ certain features ofconstruction which permit the'receptacle to be tilted with very littleexertion I also provide means for retarding the movement sufficiently toprevent a violent bumpin g of the receptacle against the truck-frame.

WVhile the center of the receptacle-floor is adequately supported by thepivot-bearings a the side portions of the said floor are preferablystrengthened and rendered suitable for supporting heavy loads by meansof a couple of longitudinally-extending trusses. The said trussespreferably consist of the angle-irons D, secured to the under side ofthe floor I), the blocks D, recessed to engage the end portions of thesaid angle-irons, and the truss-rods D having their end portionsinserted through the blocks D and provided with nuts (1. The ends of thereceptacle are strengthened by an gleiroris B, the lower ends of thelatter being secured to the end portions of the angle-irons D, and asamatter of further improvement the recesses d in .the blocks D areadapted to receive the flanges on the irons B, in addition to engagingthe end portions of the irons D. (See Figs. 4 and 5.) By thisarrangement the side portions of the floor are prevented from saggingunder a'heavy load and the receptacle rendered strong and rigid withouta material increase in the weight thereof. Also the provision of theblocks D permits ine to dispense with bolts and rivets in theconstruction of the two trusses.

What I claim as my invention is 1. A dumping-car comprising a tiltingreceptacle mounted upon a suitable truck or body frame, a side boardarranged to close the open side of the receptacle when the latter is ina horizontal position, the side board having arms which are pivotallyconnected with the said receptacle, and suitable supports or stops beingprovided for supporting the arms during the tilting of the receptacle;the point of contact between the stops and arms shifting lengthwise ofthe latter as the receptacle tilts to one side, and the side boardthereby serving at such time to counterbalance the load.

2. A dumping-car comprising a tilting receptacle mounted upon a truck orbody frame, and a couple of side boards arranged to close the oppositesides of the receptacle when the same is in a horizontal position, thesaid side boards being pivotally connected with the said receptaclebymeans of suitable arms or bars, and supports or stops being providedfor supporting the arms of either side board according to the side fromwhich it is desired to dump; the side board at the side from which theload is discharged being supported against downward movement at suchtime by the said stops, and the opposite side board beingcarried upwardand remaining in place at the side of the receptacle; the point ofcontact between the stops and the arms of the released side boardshifting lengthwise of the latter as the receptacle tilts, and the saidside board thereby serving to counterbalance the load during the tiltingof the receptacle.

3. A dumping'car comprising a tilting receptacle mounted upon a suitabletruck or body frame, a side board pivotally connected with the end boardby means of suitable arms, and a couple of rolls mounted upon the truckor body frame and adapted to support the saidarms during the tilting ofthe receptacle, the point of contact between the rolls and arms shiftinglengthwise of the latter as the receptacle tilts.

4. In a dumping-car, the combination of a suitable truck or body frame;a receptacle mounted thereon and constructed to tilt about alongitudinal axis, the axis being loboard during the tilting of thereceptacle, according to the side from which the load is discharged.

5. A dumping-car comprising a suitable truck or body frame and areceptacle mounted thereon, the said receptacle being arranged to tiltabout a longitudinal axis, and each side of the receptacle beingprovided with a truss, the latter consisting of the angleiron D, the twoblocks D, and the truss-rod D substantially as and for the purposedescribed.
